Abstract

The invention discloses an antipollution sofa leather making method. The method comprises the following steps: uniformly stirring 5-10 parts of dimethyl formamide with 2-10 parts of a color paste, 10-30 parts of wood powder and 1-5 parts of a surfactant; adding 80-100 parts of wet polyurethane resin and 150-280 parts of dimethyl formamide to obtain a wet material; impregnating a base fabric, ironing, drying, coating the wet material, solidifying, foaming, washing with water, and drying to obtain a wet base; uniformly mixing 80-100 parts of a polyurethane surface layer resin with 40-70 parts of an organic solvent, 0.5-2 parts of an assistant and 5-8 parts of an environmentally friendly toner to obtain a dry material; uniformly mixing 80-100 parts of a polyurethane binding resin with 20-60 parts of the organic solvent, 0.5-2 parts of the assistant and 5-8 parts of the environmentally friendly toner to obtain a binder; coating the dry material on release paper, drying, coating the binder, pasting the wet base, drying, cooling, and separating from the release paper to obtain a semi-finished product; and carrying out surface treatment to obtain a finished product. The method effectively improves the oil stain resistance of sofa leather.

Description

technical field [0001] The invention relates to a method for manufacturing artificial leather, in particular to a method for manufacturing anti-pollution sofa leather. Background technique [0002] When oil is spilled on the sofa surface covered with ordinary sofa leather, the oil will infiltrate inward, resulting in oil pollution marks on the surface of the sofa, which are difficult to wipe clean, and some corrosive oil stains on the sofa surface. Lead to the aging and damage of the sofa surface, greatly shorten the service life of the sofa, and bring trouble to the use of the sofa. SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned defects, the present invention provides a method for making anti-pollution sofa leather, which has a simple process, the surface of the produced product can avoid oil stains from infiltrating, facilitates quick removal of oil stains, and protects the sofa from damage. [0004] The technical scheme adopted by the presen...
